| 摘 要： | 研究了外部光反馈对垂直腔面发射激光器（VCSELs）电光特性的影响。通过计算光反馈参数对比了VCSELs与边发射激光器（EELs）的光反馈灵敏性。基于复合腔理论计算了存在外部光反馈时垂直腔面发射激光器的阈值电流及斜率效率等电光特性参数。实验结果表明，分布布拉格反射镜（DBR）反射率不同的VCSEL，在反馈率为10%的外部光反馈作用下，其阈值电流及斜率效率发生了不同程度的变化。实验结果有效验证了理论计算的结论。

| Abstract: | The influence of external optical feedback(OFB) on the light-current characteristics of the vertical-cavity surface-emitting lasers(VCSELs) was investigated theoretically and experimentally.By calculating the OFB sensitivity parameter,the OFB sensibility of the VCSELs was compared with the edge emitting lasers.Based on the compound cavity theory,the light-current characteristic parameters of the VCSELs with external OFB,such as the threshold current and the slope efficiency,were calculated.The experimental ... |
